We present herewith some natural history information such as social behavior, aggressive behavior, vocalization, food and feeing, basking and allo-grooming, time activity pattern etc. on the Nilgiri Marten Martes gwatkinsii, the endemic and threatened mustelid of Western Ghats. The conservation recommendations were also suggested for the long-term conservation of the Nilgiri Marten.

An entomological prospection to show the species composition and diurnal activity of tabanids was carried out using 15 Vavoua traps, during the rainy season (25th Sept-5th Oct and 21st Oct-9th Nov 2018), in the secondary forest [Ivindo National Park (INP)] and Village-Town sites in and around the biosphere reserve Ipassa-IRET Makokou in Gabon. In total, 839 tabanids were caught with 747 recorded at INP and regrouped under 11 species of the genus Tabanus [T. taeniola (57.76%),               T. ricardae (26.32%), T. par (5.54%), T. ruficrus (3.74%), T. socius (3.74%), T. disjunctus (2.49%), T. marmorosus (0.28%) and T. obscurehirtus (0.14%)]. However, two species of the genus Chrysops [C. dimidiatus (70.83%) and C. silaceus (29.17%)] and one species of the genus Haematopota [H. pluvialis (100%)] were only identified at INP. While in the Village-Town sites, 92 tabanids were caught and regrouped under five species of the genus Tabanus [T. ruficrus (14.13%), T. taeniola (9.78%), T. ricardae (73.91%), T. par (1.09%), and T. marmorosus (1.09%)]. Tabanids were more abundant in the forest (7.12 tabanid/trap/day) as compared to the Village-Town (0.77 t/t/d) with a statistically significant difference (P<0.05). At INP, tabanids showed a unimodal activity pattern with peak attained between 12-14H and in the anthropized milieu (14-16H) and dominated by females.

Several Pterygoplichthys species, members of the Neotropical catfish family Loricariidae, have been widely introduced outside their native ranges. In this paper, I present observations on the diel activity pattern of non-native Pterygoplichthys, tentatively identified as P. disjunctivus, with respect to their attachment and grazing on endangered Florida manatees, Trichechus manatus latirostris. The study was conducted in December 2009 at Volusia Blue Spring, an artesianal spring system in the St. Johns River basin, Florida (USA). Supplemented by information gathered during previous visits to the spring site, this study revealed that adult Pterygoplichthys are active throughout the diel period (day, twilight and night). However, juvenile Pterygoplichthys were largely nocturnal and only at night did they consistently join adults in attaching to manatees. The juveniles generally remain hidden during the day, probably responding to presence of diurnal predators, mainly birds. Differences in diel behaviors among different Pterygoplichthys size classes in Florida are consistent with published observations on loricariids inhabiting clearwater streams within their native ranges.

1997 was the third and final season devoted to gaining information on the behavior of river otters with most emphasis on nocturnal and diurnal activity. As in the 1995 and 1996 seasons, six automatic camera monitors, activated by treadle switches, were put out at sites often frequented by these animals. In addition, canoes were frequently used for daytime patrols. Field work occurred from July 8 - August 6.

The data on activity pattern and time budget of Swamp deer (Rucervus duvauceli duvauceli) were collected through instantaneous scan sampling from Dudhwa National Park, Uttar Pradesh, India Diurnal activity pattern of Swamp deer showed marked reduction in resting in winter as compared to summer. In winter resting in adult males showed polymodal pattern with peaks occurring at different hours of the day and continued throughout the day without any break. Feeding of adult females in winter and summer seasons showed a polymodal pattern with peaks occurring at different hours of the day without break. In yearling males feeding and resting was observed to occur throughout the day during winter season with peaks occurring between 11:00 to 12:00 hours. Yearling females showed continuous feeding throughout the day with peaks in different times in both the seasons. The seasonal distribution of activity patterns of the fawns showed that feeding was slightly more in summer as compared to winter. In time budget, of the expenditure on different activities, resting accounted for 63.77% and feeding 24.70%. In both the seasons resting was the major portion of their activity. Analysis showed that in all age and sex categories of Swamp deer in the Dudhwa NP, resting dominated on all other activities. The observation on endangered Swamp deer indicates synchronization in activity only in the feeding in the morning and evening hours and resting throughout the day.
